Recently in my region there is an industry called pcdn that are the CDNs of live videos, which make use of downloading torrents to balance their incoming/outcoming network allowance. However, they never really download anything and are constantly consuming all the other users' outcoming bandwidth. I hate that and want to ban them.
Their pecularities are
1. the download progress is forever 0%.
2. very high incoming flow, like 1MB/s.
What can I do to automatically ban them?
